Photodegradable polyolefins containing an aromatic ketone, ferric stearate, and a pigment

Photodegradable polyolefins containing an aromatic ketone, ferric stearate, and a pigment. Swanholm, Carl E.; Caldwell, Robert G. (Bio-Degradable Plastics, Inc., USA). U.S. US 4038227 26 Jul 1977, 10 pp. (English). (United States of America). There are some commonly used reagents like 55553-20-3 in this article. CODEN: USXXAM. CLASS: IC: C08J003-20. NCL: 260023000H. APPLICATION: US 71-195021 2 Nov 1971. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 17 Polystyrene [9003-53-6] or polyethylene (I) [9002-88-4] food packaging materials were made photodegradable and biodegradable by incorporation of an arom. ketone, ferric stearate (II) [555-36-2], and a pigment. Thus, a low-d. 1.5 mil I film (Tenite 154 DF) contg. 0.1% p,p'-di-(tert-butyl)benzophenone (III) [15796-82-4], 0.5% II, and 5% Brown No. 18109 [64060-17-9] and subjected to accelerated light exposure had 50 h puncture index <0.18 (load necessary for a 1 mm rounded probe driven at 8 cm/min to penetrate completely), compared to 0.69 for I stabilized with II and III only, and 1.11 for neat I. .

p-Conjugated systems with unique electronic structure: a case of planarized 1,3-connected polyarylmethyl carbodianion and stable triplet hydrocarbon diradical

p-Conjugated systems with unique electronic structure: a case of planarized 1,3-connected polyarylmethyl carbodianion and stable triplet hydrocarbon diradical. Rajca, Andrzej; Utamapanya, Suchada (Dep. Chem., Kansas State Univ., Manhattan, KS 66506, USA). J. Org. Chem., 57(6), 1760-7 (English) 1992. CODEN: JOCEAH. ISSN: 0022-3263.There are some commonly used reagents with their cas registry numbers 15796-82-4 and 138956-18-0 in this article. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 77 The effect of planarization on p-conjugated 1,3-connected polyarylmethyls in connection with the electronic structure and magnetic properties is examd. The synthesis, ESR and UV-visible spectroscopy, voltammetry, and magnetic studies of triplet biradical I are reported. The corresponding dianions (with Li and K as cations) are studied using NMR and UV-visible spectroscopy. .
